The 32-year-old singer was close pals with the 'Rehab' hitmaker before her death from alcohol poisoning in July, and he has become so concerned her ghost is now floating around his London home he has gone to Paris to escape the spectre.
A friend of the Babyshambles singer said: "He is utterly convinced that he has seen her ghost. A lot of people will think his visions are probably drug-induced by he claims he is clean."
However, Pete - who previously dated supermodel Kate Moss - is so worried about the alleged apparition he is refusing to come back from his French break.
During a recent London concert, Pete revealed he had written a song for Amy but he never got a chance to record it with her.
Introducing the song, the former Libertines frontman said: "Amy Winehouse asked me a while ago if I had written any new songs. I played her something, and when I had finished, she looked at me and said, 'Is that it? Is that all you've got?' "
The song he played was a slow, acoustic led number, and although the lyrics were hard to make out they include the line "oh Amy, she won't be around tonight".
